铝蜂窝的动态力学性能及影响因素
Dynamic mechanical properties of aluminum honeycomb and its effect factors
摘要
Abstract
The dynamic mechanical properties of hexagonal aluminum honeycombs with various cell configurations are studied by employing the explicit dynamic numerical simulations. The deformation mode and the crushing strength of the honeycombs, as well as the influence factors are discussed. Five kinds of cell configurations are acquired by changing the cell-wall angle, and three levels of impact velocity are involved in the numerical simulations. The results show that under the quasi-static deformation mode, the crushing strength of the honeycombs is dominated by the cell configuration. Once the honeycomb's deformation turns into the dynamic mode, the inertia effect is notable and becomes the deciding factor of the honeycombs' crushing strength, while the influence of the cell configuration is inconspicuous. Under the transitional mode, the crushing strength of the honeycombs is determined by both the inertia effect and the cell configuration simultaneously. Moreover, the higher the impact velocity, the more significant the proportion inertia effect.关键词
